CORE
The Jack™ core was designed as a low RG symmetric core with a high differential. The low RG engages in the mid-lane assisting in ball motion, and the high differential increases track flare potential giving the ball more opportunity to grip the backend while using standard layouts.

BALL MOTION
With its 2000 Siaair Micro Pad finish, the Lethal Revolver unites the proven Propel X Solid coverstock and the Jack low RG core to produce a ball motion that clears the front part of the lane and produces a strong yet predictable ball motion from the breakpoint through the pins especially for bowlers with lower rev rates.

REACTION SETUP
The Lethal Revolver can be drilled using the standard drilling techniques developed for symmetric bowling balls.

LIGHTWEIGHT ENGINEERING
At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
